Previous Year Question

Among the given options, Dolphin is the expected answer. Dolphins are marine mammals with highly developed cognitive abilities. According to NOAA, dolphins are among the most intelligent animals on Earth, and members of the dolphin group have also demonstrated self-recognition in the mirror self-recognition test.

Dolphins exhibit abilities such as learning, problem-solving, social cooperation and complex communication, which place them among highly intelligent non-human mammals.

Important fact: The wording of the question is not scientifically precise. Humans are also mammals, and there is no single universally accepted scientific measure that ranks all species as the “most intelligent.”
